Description

Technical Field

[0001] This utility model relates to the field of Dendrobium cultivation technology, and in particular to a high-efficiency shading device for Dendrobium cultivation. Background Technology

[0002] Dendrobium requires a relatively strict environment to grow, with specific requirements for temperature, humidity, and light. The suitable growth temperature for Dendrobium is 15-30℃, the air humidity needs to be maintained at 60-80% for a long time, and it also needs a diffused light environment. The light requirements also vary at different growth stages.

[0003] Existing technology discloses a shading device for Dendrobium officinale cultivation, including a fixed plate, a shading mechanism on the top of the fixed plate, an irrigation mechanism on the side of the fixed plate, and an adjustment mechanism at the bottom of the fixed plate. The shading mechanism includes a connecting plate fixedly connected to the side of the fixed plate, a drive motor mounted on the side of the connecting plate, a rotating rod fixedly connected to the output shaft of the drive motor, the rotating rod extending into the connecting plate and rotatably connected to the connecting plate, and a fixing sleeve fixedly connected to the outer surface of the rotating rod. By setting up the shading mechanism, part of the shading plate can be placed on top of the Dendrobium officinale. Through the cooperation of a time sensor and a controller, the shading plate can be rotated over time, thereby shading the Dendrobium officinale while avoiding the phenomenon of all the shading cloth being fixed on top of the Dendrobium officinale, thus avoiding poor ventilation and increasing the growth rate of Dendrobium officinale.

[0004] The shade cloth of the above-mentioned device is fixed on the device. The light intensity varies throughout the day. When the light is strong, the Dendrobium needs to be shaded. At other times, in order to ensure that the Dendrobium can receive light normally, the shade cloth is often located on the top of the Dendrobium, which affects ventilation.

[0005] Therefore, it is necessary to provide an efficient shading device for Dendrobium cultivation to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a high-efficiency shading device for Dendrobium cultivation that allows for easy installation and removal of shading cloth.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A high-efficiency shading device for Dendrobium cultivation includes: a greenhouse frame and a shading cloth installed inside the greenhouse frame;

[0009] The greenhouse frame includes a supporting frame, the lower part of which is in contact with the ground is a column, and the upper part of the column is a crossbeam.

[0010] The sunshade cloth includes a sunshade net arranged in a horizontal direction. Several sliding seats can be detachably installed on both sides of the sunshade net. A connecting rope is provided between two sliding seats. A first pull rope is also provided on the sliding seats at both ends.

[0011] The slide block is slidably mounted on the crossbeam.

[0012] Preferably, a second pull rope is also provided on the slides located at both ends.

[0013] Preferably, the crossbeam consists of a beam strip fixedly installed on the column and a slide rod fixedly installed on the beam strip, and the slide block is slidably installed on the slide rod.

[0014] Preferably, the slide is provided with a hook, and the edge of the shade net is hung on the hook.

[0015] Preferably, one end of the hook is a threaded section, and the threaded section is detachably connected to the slide.

[0016] Preferably, the slide block is provided with a steering hole, through which the second pull rope can pass.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This utility model achieves the effect of folding and unfolding the shade net by setting up a sliding seat and other related components, adjusting the light intensity required by Dendrobium at different times of the day. At the same time, the connection method between the hook and the shade net makes it convenient to install and disassemble the shade net and the hook, so that staff can change shade nets with different shade capabilities according to the season.

[0019] (2) This utility model achieves the effect of folding one side of the sunshade net by setting a second pull rope and a turning hole, thus saving manpower;

[0020] (3) By setting the hook and the slide to be detachable, this utility model makes it easy to add more hooks to the slide later. Different sizes of greenhouse frames have different widths and lengths, and the required shade nets are different sizes. At the same time, different types of shade nets may have different weights. Shade nets with greater weight need to be hung on more hooks to meet the stability requirements. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] Dendrobium orchids have strict light requirements, needing primarily diffused light and avoiding direct sunlight. The light intensity should be controlled within the range of 1800-1900 lx. During the growing season, approximately 60% shade is typically needed, while seedlings require over 70% shade, which can be achieved through shade netting or a shady environment. Light conditions need adjustment according to the season: in spring and autumn, natural light can be increased to 9-10 hours daily, and shading reduced to 40-50%; in the high temperatures of summer, 60-70% shade is required, and in extreme cases, complete coverage with shade netting is necessary; in winter, shading can be reduced to 20-30%, extending the light duration to promote nutrient accumulation. Special varieties such as Dendrobium officinale are more sensitive to light; seedlings require over 70% shade, and mature plants should be kept under 60% shade during the growing season. Strong light can easily cause leaf burn or premature pruning. When cultivating indoors, it can be placed near a bright window. If there is insufficient light, full-spectrum plant lights can be used to supplement the light, but the light fixtures must be kept at least 30cm away from the plants to avoid local scorching. Specific light management needs to be flexibly adjusted according to the characteristics of the variety and the growth stage. Therefore, the light requirements of Dendrobium vary at different times of the day and in different seasons of the year. Shading cloths need to be used flexibly according to the actual situation to meet the light requirements of Dendrobium.

[0027] First embodiment:

[0028] like Figure 1 As shown, the present invention provides a high-efficiency shading device for Dendrobium cultivation, comprising: a greenhouse frame 10 and a retractable and adjustable shading cloth 20 installed inside the greenhouse frame 10;

[0029] Specifically, such as Figure 2The diagram shows a partial structural schematic of the connection between the greenhouse frame 10 and the shade cloth 20. The rest of the parts are the same as this part. The greenhouse frame 10 includes a frame body 11 that supports the upper plastic cloth or glass plate. The part of the frame body 11 that contacts the ground is a column 111. The column 111 transfers the upper load to the ground. The upper end of the column 111 is horizontally welded with a crossbeam 12 along the longitudinal direction of the greenhouse frame 10. The crossbeam 12 consists of two parts. The part that contacts and is welded to the column 111 is a beam 121. The smooth round rod fixed to the other side of the beam 121 is a slide bar 122. This part is the track for the shade cloth 20 to slide.

[0030] The shade cloth 20 includes a horizontally arranged shade net 21. The shade net 21 is a conventional black plastic mesh, which has different specifications and different light-blocking capabilities. Its edges are sealed with piping. On the other hand, such as... Figure 3 As shown, the component installed on the slide rod 122 and that can slide on it is the slide seat 22. It has a groove on one side for inserting the slide rod 122, and four through holes on its surface. Two of the through holes are respectively inserted into hooks 25 and welded and fixed. The hooks 25 face upwards, and the edge of the shade net 21 is hung on the hooks 25. The greenhouse frame 10 has the above structure on both sides. That is, the two sides of the shade net 21 are respectively hung on the hooks 25 on the left and right sides of the greenhouse frame 10 to keep it horizontal. In addition, two adjacent slide seats 22 are connected by a connecting rope 23. One end of the connecting rope 23 is tied to the hook 25 of one slide seat 22, and the other end is tied to the hook 25 of the other slide seat 22. Since the greenhouse frame 10 is relatively long, the shade cloth 20 is not a whole piece but is divided into several small sections and installed on the greenhouse frame 10. Each small section has the same structure. The hooks 25 of the two ends of the slide seats 22 of a small section are also provided with a first pull rope 24.

[0031] The groove of the slide block 22 is slidably mounted on the slide rod 122, so as to... Figure 2 As shown in the diagram, after pulling the two first pull ropes 24 on the left and right, the two outermost slides 22 on a small section are moved to the left and right respectively. Similar to pulling a curtain, the shade net 21 hanging on the hooks 25 of the slide 22 unfolds. Then, as the slide 22 moves further, the connecting ropes 23 connecting the adjacent slides 22 begin to straighten, causing their slides 22 to move. Finally, when all the connecting ropes 23 are straight, the shade net 21 is fully unfolded. Finally, the first pull rope 24 is tied to the post 111 for fixation. When the external light intensity is low, pulling the first pull rope 24 in the opposite direction will result in the opposite movement process, and the shade net 21 will eventually retract.

[0032] By setting up sliding base 22 and other related components, the shade net 21 can be retracted and unfolded, adjusting the light intensity required by Dendrobium at different times of the day. At the same time, the connection between hook 25 and shade net 21 makes it easy to install and remove shade net 21 and hook 25, thus making it convenient for staff to change shade net 21 with different shading capabilities according to the season.

[0033] Second embodiment:

[0034] like Figure 3 As shown, a second pull rope 26 is attached to the hook 25 at both ends of the slide 22, as... Figure 2 As shown, the slide block 22 is also provided with a through hole for the second pull rope 26 to pass through, which is a turning hole 221, so as to... Figure 2 As shown in the diagram, when the second pull rope 26 is pulled to the left (the other end of the second pull rope 26 is attached to the hook 25 of the rightmost slide 22), the rightmost slide 22 is pulled to the left. Due to the presence of the turning hole 221, the pulling force of the second pull rope 26 on the slide 22 remains horizontal, providing shade. As the pull is further extended, the rightmost slide 22 gradually pushes the slides 22 on its left side to move to the left. At the same time, the shading net 21 on the slide 22 also retracts to the left.

[0035] By setting a second pull rope 26 and a turning hole 221, the effect of retracting one side of the sunshade net 21 through a single-person interface can be achieved, saving manpower.

[0036] Third embodiment:

[0037] like Figure 3 As shown, one end of the hook 25 is a threaded section 251, and the through hole on the slide 22 is a threaded hole. The threaded section 251 is installed in the threaded hole on the slide 22 that is compatible with it.

[0038] By making the hooks 25 and the slide 22 detachable, it is easy to add more hooks 25 to the slide 22 later. Different sizes of greenhouse frames 10 have different widths and lengths, and therefore require different sizes of shade nets 21. At the same time, different types of shade nets 21 may also have different weights. Shade nets 21 with greater weight need to be hung on more hooks 25 to meet the stability requirements.

[0039] When in use, similar to pulling a curtain, two people stand at the left and right ends of the device and pull the first pull rope 24 to the sides to gradually straighten the sunshade net 21 to a horizontal state. Finally, the first pull rope 24 is tied to the post 111.

[0040] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
